Singh et al. Cover crops and tillage effects on carbon nitrogen pools A lysimeter study 2021
Drs. Karl Williard, Jon Schoonover of Southern Illinois University and Gurbir Singh and Gurpreet Kaur from the Delta Research and Extension Center at Mississippi State University had their original research published in Vadose Zone Journal, published by the Soil Science Society of America.
Dr. Shalamar Armstrong’s research near Bloomington, Ill. takes a close look how adjusting N timing overcame the usual yield lag in corn planted into cereal rye cover crop.
Dr. Shalamar Armstrong with Purdue University leads this multi-institute research project that closely examines the impact that cereal rye cover crop has on nutrient loss.

David and Jim Isermann share research on their farm using struvite as an alternative to traditional phosphorus field applications. Partners from Farm Bureau, Isermann Farms, University of Illinois, Illinois NREC and Soil Health Partnership all play a role in studying the Isermanns’ LaSalle County plot.

Lowell Gentry, Dan Schaefer and Eric Miller are studying how installing a woodchip bioreactor at the edge of a field, along with planting cover crops might limit nutrient loss.
Can drainage depth and spacing be optimized to minimize the nutrient losses and maximize crop production?
It’s not as complicated as it sounds. DNRA conserves Nitrogen within the system. Since DNRA takes nitrate and converts it to ammonium, it does not produce N2 or N2O.
Dr. Laura Christianson, along with her colleagues from the University of Illinois, are exploring various options of drainage water management. “Drain only what is necessary for good trafficability and crop growth — and not a drop more?
